I was thinking about the top leaderships in the modern history. And, I think most of the top leaderships seem to be introverted leaders - King Mahendra, King Birendra, Girija Koirala, Sher Bahadur Deuba, Manmohan Singh, Madhav Nepal, Jhalanath Khanal, Bamdev Gautam, KP Oli.

However, I think BP Koirala was extroverted and Prachanda is also extroverted.

What do you think? It is just my speculation based on what I have heard about them and seen on the news.
